The 1999 Bob Jane T-Marts Super Touring 500 was a motor race staged at the Mount Panorama Circuit, Bathurst, New South Wales, Australia on 3 October 1999.
The race was very heavily weather affected with rain wreathing the circuit for much of the day, earlier blighting the Bob Jane T-Marts V8 300 race held for a combined field of AUSCARs and Future Touring Cars.
Paul Morris avenged his disqualification from victory in the 1997 AMP Bathurst 1000 taking victory over the two-car factory supported Volvo team, Jim Richards driving solo as Cameron McLean was unable to take his scheduled middle stint because of the weather and because of tyre issues, and Craig Baird and Matthew Coleman.
Fourth place and leading independent driver was young New Zealander Mark Porter who had impressed team owner Mike Downard that he kept Porter in the car rather than take his own turn at the wheel.
Leading independent team Knight Racing saw the Dean Canto / Leanne Ferrier buried in a sand trap at The Chase while the lead car of Peter Hills / Ron Searle struggled with water leaks and electrical issues.
